QUESTION 1
Which assessment finding is characteristic of acute appendicitis?
A. Rovsing sign
B. CVA tenderness
C. Murphy sign
D. McBurney point hyperesthesia
Correct Answer: A. Rovsing sign
Rationale: Pressing in the left lower quadrant causes pain in the right
lower quadrant, known as Rovsing sign, which indicates peritoneal
irritation and appendicitis.
QUESTION 2
Which medication class is considered first-line treatment for chronic
heart failure with reduced ejection fraction to reduce mortality?
A. Calcium channel blockers
B. ACE inhibitors
C. Direct-acting vasodilators
,D. Loop diuretics
Correct Answer: B. ACE inhibitors
Rationale: ACE inhibitors block the renin-angiotensin-aldosterone
system, decreasing preload and afterload to improve survival in heart
failure.
QUESTION 3
A patient presents with a resting tremor, bradykinesia, and rigidity.
Which neurotransmitter deficiency is primarily responsible for these
symptoms?
A. Acetylcholine
B. Serotonin
C. Dopamine
D. Norepinephrine
Correct Answer: C. Dopamine
Rationale: Parkinson disease involves the degeneration of dopaminergic
neurons in the substantia nigra, leading to a deficiency of dopamine in
the basal ganglia.
QUESTION 4
Which breath sound is expected when auscultating over the major
bronchi of an adult without respiratory pathology?
A. Vesicular
,B. Bronchovesicular
C. Stridor
D. Wheezing
Correct Answer: B. Bronchovesicular
Rationale: Bronchovesicular breath sounds are heard over the major
bronchi and have a moderate pitch and intensity with equal inspiration
and expiration phases.
QUESTION 5
What is the primary mechanism of action of nonsteroidal anti-
inflammatory drugs (NSAIDs)?
A. Inhibition of cyclooxygenase enzymes
B. Stimulation of opioid receptors
C. Stabilization of mast cell membranes
D. Blockade of histamine H1 receptors
Correct Answer: A. Inhibition of cyclooxygenase enzymes
Rationale: NSAIDs inhibit COX-1 and COX-2 enzymes, thereby blocking
the synthesis of prostaglandins involved in inflammation, pain, and
fever.
QUESTION 6
Which cranial nerve is tested when assessing the patient's ability to
shrug the shoulders against resistance?
, A. Cranial Nerve IX
B. Cranial Nerve X
C. Cranial Nerve XI
D. Cranial Nerve XII
Correct Answer: C. Cranial Nerve XI
Rationale: Cranial nerve XI is the spinal accessory nerve, which
innervates the sternocleidomastoid and trapezius muscles responsible
for shoulder shrugs and head rotation.
QUESTION 7
Which laboratory value is most indicative of iron deficiency anemia?
A. Elevated mean corpuscular volume
B. Decreased serum ferritin
C. Elevated total iron-binding capacity
D. Decreased red cell distribution width
Correct Answer: B. Decreased serum ferritin
Rationale: Serum ferritin reflects total body iron stores and is the most
sensitive and specific test for diagnosing iron deficiency anemia.
QUESTION 8
Which type of hypersensitivity reaction is mediated by IgE antibodies
and involves mast cell degranulation?
